BLACK HOLE

A black hole is a region of space in which gravity exerts such an enormous pull that nothing—not even light—can escape. That’s the simple definition of a black hole. But if you talk to a physicist, they’ll also describe a black hole as a region of very severely curved space-time—so sharply curved, in fact, that it’s “pinched off,” so to speak, from the rest of the universe.

This idea of curved space-time goes back to the work of Einstein. It was Einstein who put forward his theory of gravity, known as the general theory of relativity. According to the theory, matter curves, or distorts, the very fabric of space. A small object like Earth causes only a small amount of distortion; a star like our Sun causes more warping. And what about a very heavy, dense object? According to Einstein’s theory, if you squeeze enough mass into a small enough space, it will undergo a collapse, forming a black hole; the amount of warping will become infinite.

The boundary of the black hole is known as the “event horizon”—the point of no return. Matter that crosses the event horizon can never return to the outside. In this sense, the inside of a black hole is not even a part of our universe: Whatever might be happening there, we can never know about, since no signal from the inside can ever reach the outside. According to general relativity, the center of a black hole will contain a “singularity”—a point of infinite density and of infinitely curved space-time.

But what is "infinite density" and "infinite curved space time?" 

A personal theory is that it death.

The human body is made up of twisted molecules that produce cells that harness and retain energy. In one respect, each of us is their own universe. It is a self-contained complex system of checks, balances, functions and movements. Science thinks it knows how the human body works - - - but cannot produce it artificially by combining chemicals and energy in a test tube.

The spark of life is unique. So should be the amber of death.

In major religions, when a person dies they are "reborn" in the afterlife, whether it be heaven with the spirits of one's ancestors and loved ones, to be reincarnated as another life form on Earth. In some ways, this is a comfort to the living that death itself has a purpose. A continuation of life is a noble goal.

But if at the end, all energy in a person's body combines and pools itself in one last gasp to breathe life in the organic host, with such density as to leave the body - - -  one could say that a person's soul has left on another journey. If the soul is an encoded energy source, it could carry a person's thoughts, memories, stories, loves, hates, emotions, and dreams to the vastness of eternity. It could replay those life stories forever, or combine them with new souls to create new memories.

The latter seems to fall into the pattern of the final season of LOST, with the souls in the sideways world recombining to make new memories.
